ADM233LANZ

Overview

The ADM233LANZ is a CMOS RS-232 transceiver from Analog Devices, designed for single 5 V operation. It integrates two drivers and two receivers with internal charge pump converters, eliminating the need for external capacitors. The device supports data rates up to 120 kbps and provides ±9 V output swings. It operates within an industrial temperature range of -40°C to +85°C and features Schmitt trigger inputs for noise immunity.

Feature Summary

• Integrated charge pump voltage converters generate required supply levels without external components
• Schmitt trigger receiver inputs provide hysteresis for reliable signal reception in noisy environments
• Internal pull-up and pull-down resistors on inputs ensure defined logic states when unconnected

Applications

• Computers
• Peripherals
• Modems
• Printers
• Instruments

Procurement Notes

Verify the specific suffix 'L' indicates the industrial temperature grade (-40°C to +85°C) rather than commercial grade. Confirm package type matches design requirements, as the datasheet specifies PDIP-20 for this family member. Ensure ordering documentation aligns with the manufacturer's current revision C specifications.

Selection Notes

Select this component when PCB space is limited due to its lack of external capacitor requirements. It is suitable for applications requiring full-duplex communication at speeds up to 120 kbps. Verify that the system operates strictly from a single 5 V supply, as dual supplies are not supported by this specific part number.

Part Context

This part belongs to the ADM2xxL family of enhanced CMOS RS-232 transceivers. It serves as a space-saving alternative to standard versions by incorporating internal charge pumps. The 'A' suffix typically denotes the industrial temperature range, while 'J' would indicate commercial range.
